Alpinestars GP Tech v4 Leather Suit - Black/White US 38 / EU 48 | Part 3156822-12-48

The Alpinestars GP Tech v4 Leather Suit is engineered for professional racing performance, combining lightweight construction with advanced protective features. Crafted from high-grade kangaroo leather in high flex zones such as arms, hips, and abdomen, this suit offers exceptional flexibility, ensuring maximum movement and comfort during high-intensity rides. The race-grade bovine leather components further enhance durability and contribute to weight reduction, making it an ideal choice for competitive riders. The suit's design incorporates extended stretch paneling around the chest, inner arms, crotch, and back leg, providing improved fit and enhanced freedom of movement while maintaining structural integrity.
Alpinestars has integrated innovative MATRYX® structural panels across critical areas including the thighs, abdomen, chest, and back hump. These panels deliver superior mechanical resistance to tearing and abrasion, as well as excellent ventilation properties, thanks to their parametric performance design. Additionally, the suit features reinforcement to prevent heat transfer, ensuring rider comfort in varying conditions.
Equipped with advanced thermal management technology, the suit incorporates the Cool-iR Tech treatment embedded within the leather. This system reflects infrared rays from the sun to reduce heat build-up, maintaining an optimal body temperature. The suit's race fit is highly pre-curved to optimize aerodynamics and rider ergonomics, with strategic perforations on arms and legs that promote airflow and cooling. For added convenience, a zippered detachable short-leg liner with Polygiene® treatment ensures long-lasting freshness and easy maintenance.
The GP Tech v4 is also Tech-Air® ready, with a dedicated slot on the left forearm to accommodate the Tech-Air® 10 Airbag System, sold separately. Its extended hip protection and reinforced lower leg panels with high-performance PU derived from MotoGP enhance impact resistance and ventilation, offering a lightweight yet protective racing suit. Features such as replaceable elbow sliders, internal GP-R Lite armor for comfort and extended coverage, and Bio-Flex Race hip armor provide comprehensive impact protection. An internal paddock waist hook system keeps the suit securely in place when off the bike, while strategic perforations and advanced materials ensure optimal airflow and temperature regulation. The suit is finished with a convenient, zippered, detachable short-leg liner for comfort during off-track activities, making it a top-tier choice for serious racers seeking protection, performance, and comfort.
